The founder of eBay Pierre Omidyar has been tweeting about how he founded the site back in 1995. He said: ’18 years ago this weekend I was not sleeping much and writing a lot of code for a new website. Now that it’s turned 18, I wonder if it’s time to kick it out of the house?’

Here are 18 things you probably didn’t need to know about the world’s biggest online marketplace:

1. eBay’s original name was Auctionweb and the service was just one feature of Omidyar’s website which also included a tribute to the Ebola virus.

2. The name comes from Echobay, the name of Omidyar’s company chosen because he thought it just sounded cool. That web domain had already been snapped up by a Canadian mining firm so he settled on eBay as second best.
